Help with Rims and Wheels

I have 17x8" I need everyone who has done this to please fill me in, I want to put 275/40/17 MT ET Street radials (which are 1" shorter and call for a 9" rim) on my 17" rims...If you have done this and had no problems fill me in pls.

the biggest problem with the 235/55/17 is that they are 27" and that is hard to find in a 200 or less treadwear...or a street rdrag radial..245/45/17 are even shorter

the best I've found is a bridgestone potenza 235/55/17 with a 140 tread wear...


Please help me decide or fill me in

Thanks
